Patent DE-3124347-A1 (DE)
Title: Farrowing cage for pig pens
Inventor: KLOECKER KLAUS
IPC: A01K1/02
Filed: 1981-06-20
Abstract: The invention relates to a farrowing cage for pig pens, the cage having the function of sufficiently restricting the freedom of movement of a sow in order to protect the young animals. It has been possible to erect farrowing cages, used up until now, only unsatisfactorily in various positions of a pig pen, that is to say either only with the sides parallel to a delimiting wall of a pig pen or obliquely in conjunction with a corner trough, the cages in each case having a rectangular outline. For better adaptation to spatial conditions, experience calls, however, for an erection of the cage with an outline in the form of a parallelogram, this being prevented, in the case of the known embodiments, by rod arrangements above the cage which prevent the sow from standing up. The invention solves this problem in that the rod arrangement over the cage is configured in the manner of an essentially U-shaped, horizontal spring frame (13), whose leg parts (30), arranged parallel to the side-wall parts (12) of the cage (10), can be changed in length separately in order to permit a common, lateral pivoting-out of the side-wall parts in one direction or the other. The open end, remote from the top frame (11), of the cage (10) is, in this arrangement, closed by a separate door part (14) which is to be arranged at right angles or at a slant. The invention is used predominantly for pig pens which are erected in rows along a feed passage. <IMAGE>

Patent DE-3126599-A1 (DE)
Title: Fish catching appliance
Inventor: BUBECK HELMUT
IPC: A01K77/00
Filed: 1981-07-06
Abstract: A fish catching appliance consists of a supporting arm and a net secured to a ring which is attached on the supporting arm to be capable of pivoting through about 180 DEG  relative to the latter and can be locked in its outward pivoted position. The mounting of the ring/net unit on the supporting arm is to be improved in comparison with the previously known mountings. This is achieved in that the two ends of the ring are each mounted in a rotating member, the two rotating members are each rotatably mounted in a part, designed as a cylindrical bushing, of a double-armed housing provided with a connecting piece for fixing on the support arm and are subject to the action of a spring, and in that the two cylindrical bushing parts of the housing each contain a recess which extends approximately over half the circumferential length of the cylindrical bushing parts and, in their end region defining the outward pivoted position of the ring, makes a transition into an outward-directed cut-out in which the respective ring end engages as a consequence of the spring force acting on the associated rotating member.

Patent DE-3141873-A1 (DE)
Title: Method for indicating site data in a map device
Inventor: OLBRICH BERND DIPL-ING
IPC: G01C21/22
Filed: 1981-10-22
Abstract: The invention relates to a method for indicating site data. These are supplied by a location-finding device and indicated in a map device by means of a bar cross. For this purpose a comparison device determines a deviation between site data supplied and indicated and automatically corrects the bar cross in accordance with this deviation. If an error between the indicated and actual site is determined, the bar cross of the indicating device can be adjusted in the sense of a correction. During a later correction of the site data supplied by the location-finding device, which essentially corresponds to the adjustment, this is compared according to the invention with the adjustment and in the case of an approximate correspondence, the automatic correction of the bar cross is suppressed for this correction or, alternatively, the adjustment is cancelled and the correction is carried out on the map device. <IMAGE>

Patent DE-3147017-A1 (DE)
Title: Catch and manoeuvring device for floating bodies
Inventor: HENNING ALFRED DR ING
IPC: B63B35/70
Filed: 1981-11-27
Abstract: The catch and manoeuvring device arranged on the bow of motor boats consists of one or two vertically pivotable catch arms which seize the floating bodies, in particular a folding floating-bridge section, from above, which floating bodies float freely over the edge of the boat, and secure the floating body against a support acting from the front or from below. Laborious mooring of the motor boat to the floating body by means of ropes in the conventional nautical manner, for which purpose a multiman crew is required, is unnecessary with this device. The moving of the launched floating-bridge sections and the floating into line of the floating bridges to be constructed can be carried out very quickly and safely by the boatman alone using the catch and manoeuvring device. The use of this device guarantees quicker, reliable linking with much less use of personnel.

Patent DE-3148321-A1 (DE)
Title: Device for heat-treating horizontally guided, web-shaped products
IPC: F26B21/02
Filed: 1981-12-07
Abstract: The invention relates to a belt drier or tentering frame, in which the treatment air, which is circulated in the circuit, is supplied by means of nozzle boxes which are arranged above and below the material web and extend across the working width and to which the treatment air is supplied by means of an axial fan arranged on the longitudinal side of a treatment compartment. Before acceleration of the treatment air by the fan, it is heated with the aid of direct flame heating. The flame gases pass via a burner pipe arranged around the fan intake fitting into the treatment air drawn in by the fan. The burner pipe is passed around on all sides by the treatment air to be heated and is thus cooled. An upstream sheet metal construction which swirls the air flowing in and the fact that the burner pipe is flowed around ensure the turbulence necessary for uniform mixing of the combustion gases with the treatment air to be heated. <IMAGE>

Patent DE-3150942-A1 (DE)
Title: Adjustable double throttle valve
Inventor: STEPRATH WERNER ING GRAD
IPC: F16K47/04
Filed: 1981-12-23
Abstract: An adjustable double hydraulic throttle valve (10, 40) is proposed which can be changed over from a counteracting valve to a unidirectional valve by assembling its control member (18) in a turned-around position. On the periphery of the control member (18), in each case two control edges (28, 31; 29, 32) are formed at a distance A from one another on opposite sides by one sloping groove (26, 27) each, while the grooves (26, 27) and the fixed control ports (15, 16) are in each case axially offset from one another by half the distance A. When the control member (18) is assembled in the housing (11) in a position turned through 180 DEG  and axially offset by half the distance A, the control edges (29, 31), lying towards the operating side (25), of both grooves (27, 26) produce a unidirectional operating mode of both individual resistances (35, 36) in the double throttle valve. <IMAGE>
Patent DE-3202110-A1 (DE)
Title: Treatment plant for substances heavier and lighter than water
Inventor: RIKER RUDOLF ING GRAD
IPC: B01D21/00
Filed: 1982-01-23
Abstract: A treatment plant is described for separating mixtures of substances heavier and lighter than water with the aid of a liquid, preferably water, and for making them harmless or re-usable. After the settlable solids have been removed in known treatment plants, using mechanical means, as in the non-metallic minerals industry, pit and quarry industry, building materials industry and ceramics industry, no methods have hitherto been known to separate also substances lighter than water (floaters) in the same plant with minimum expenditure in terms of equipment. The invention indicates ways in which, using various treatment systems for constituents heavier than water, the substances lighter than water can likewise be purified and discharged. This is demonstrated with the example of a trough/drag chain solution, system A, a rotating wash drum system B and a stirred settling tank connected downstream of any desired separating device.
Patent DE-3205974-A1 (DE)
Title: Snowplough
Inventor: HAERING THEODOR
IPC: E01H5/06
Filed: 1982-02-19
Abstract: The share (1) of the snowplough is equipped at its lower end with a fender (2) which is held in its working position by a torsion spring (5). When the fender strikes an obstacle, it can pivot rearwards about the axle (3). So that it does not need to raise the plough during this pivoting movement, it is held together with the restoring spring of a rocker (4) which allows the fender to raise during its pivoting movement. The gap (S) remaining as a result of this constructive arrangement between the lower edge of the ploughshare (1) and the top side of the fender (2) is bridged by a rubber element (12). The rubber element (12) serves at the same time as a restoring spring for the rocker (4). Instead, a separate restoring spring can also be attached. <IMAGE>

Patent DE-3215503-A1 (DE)
Inventor: WENGER HELMUT
IPC: B26F3/08
Filed: 1982-04-26
Abstract: An electrically heated excising or cutting tool for cutting rubber, plastic, and the like includes a handle carrying at one end a cutting blade of flat resistive material through which current flows to produce heat. The blade is substantially U-shaped with limbs having free ends clamped to contact pieces on the handle connected to the poles of a power supply. The blade is bent at right angles to the plane of the flat material in the region between the free ends of the limbs and the bight portion of the U-shaped blade to define a cutting region having a first limb disposed in a cutting direction from the second limb. The first limb is reduced in cross-sectional area at the bend to increase the production and concentration of heat in the cutting region to counteract the increased heat dissipation in the cutting region caused by the accumulation of excised material thereat. A cooling device is provided on the handle for cooling the parts of the blade away from the cutting region to reduce the transfer of heat to the handle and to simultaneously result in an increase in heat generation in the cutting portion of the blade due to the increase in electrical resistance in that region. The contact pieces are provided with openings to further reduce heat transfer to the handle.
Patent DE-3217871-A1 (DE)
Title: Heat treatment furnace
Inventor: KELLER HARTWIG DR ING
IPC: F27D99/00
Filed: 1982-05-12
Abstract: The invention relates to a heat treatment furnace having a movable partition between two regions differing in temperature. In the case of turntable furnaces, for example, a partition is arranged between the immediately adjacent regions for charging and unloading. However, if a timely removal of the material being heat treated did not take place, and also a safety device which would have been able to release the vertical lifting of the partition failed to operate, the partition would be damaged. The partition was hitherto made of heavy brick material and could only be moved comparatively slowly and by high drive power. Particularly to eliminate the danger of damage, the invention proposes that the partition has on its side facing the region of higher temperature a heat-barrier layer of ceramic fibre material, and can be deflected in the transport direction by the material being heat treated, if this striking against it.
